Is that a Saddle?

I know this isn't the greatest photo - it was dark and I only had my old point and shoot - but this is the Pengrowth Saddledome, home of the Calgary Flames.
It's called the Saddledome becasue it was designed in the shape of a saddle...Calgary being Cowboy country and all that.
And yes...there is a guy in a cowboy hat in the picture. Lots of people wear them in Calgary - even when it's not Stampede time.
